Earth's Layers Mini Flashcard

Front

What is the outermost layer of the Earth called?

Back

The outermost layer of the Earth is called the Crust.

Front

What is the layer of the Earth that includes the crust and the uppermost part of the mantle?

Back

The layer that includes the crust and the uppermost part of the mantle is called the Lithosphere.

Front

What is the layer of the Earth located beneath the lithosphere that is semi-fluid and allows for tectonic plate movement?

Back

The layer located beneath the lithosphere that is semi-fluid is called the Asthenosphere.

Front

What is the layer of the Earth that is liquid and surrounds the inner core?

Back

The layer of the Earth that is liquid and surrounds the inner core is called the outer core.

Front

What is the innermost layer of the Earth, which is solid and composed mainly of iron and nickel?

Back

The innermost layer of the Earth is called the inner core.

Front

What are the two main types of Earth's crust?

Back

The two main types of Earth's crust are continental crust and oceanic crust.

Front

What is the primary composition of the Earth's crust?

Back

The primary composition of the Earth's crust includes silicate minerals, primarily granite in continental crust and basalt in oceanic crust.

Front

How does the temperature change as you move from the crust to the inner core?

Back

As you move from the crust to the inner core, the temperature increases significantly, reaching up to 5,700 degrees Celsius in the inner core.

Front

What is the significance of the lithosphere in plate tectonics?

Back

The lithosphere is significant in plate tectonics because it is broken into tectonic plates that float on the semi-fluid asthenosphere and are responsible for geological activity.

Front

What is the role of the outer core in Earth's magnetic field?

Back

The outer core plays a crucial role in generating Earth's magnetic field through the movement of molten iron and nickel.
